Sliding device for doors and wardrobe doors provided with multiple adjustments

Abstract

A sliding device for doors and (24) wardrobe doors provided with multiple adjustments consists of a carriage or slider (10), provided with rollers or bearings (22) for sliding the doors to which a profile section (28) is secured having an embossed and shaped portion (22{circumflex over ( )} of a shape complementary to the profile section of said rollers (22). The carriage or slider (10) comprises a first body or front body (12), having a substantially rectangular plan, and a second body or rear body (14) intended to be connected to the first front body (12); said rear body (14) is provided with opposed substantially cylindrical appendages (16, 18) with a vertical passing-through hole (32) in which respective cylindrical bodies are inserted along which an offset and passing-through threaded hole (36) is bored, to form as many eccentrics (34). In each of the holes (36) a threaded stem or screw (38) is entered, which protrudes from the upper side of the front body (12) on which corresponding holes or slots (32y) are bored.

The invention claimed is: 
     
       1. A sliding device for doors ( 24 ) provided with multiple adjustments consisting of a carriage or slider ( 10 ) provided with rollers or bearings ( 22 ), comprising a profile section ( 28 ) with a substantially “L”-shaped section, constrained to the front side of the door ( 24 ) facing a wall ( 26 ) on which a passage area ( 30 ) is created, abutted to a lowered portion formed at the upper edge of the same door ( 24 ) and provided with an embossed and shaped portion ( 22 ′) having a shape complementary to the profile section of the rollers along which it slides, characterized in that the carriage or slider ( 10 ) comprises a first body or front body ( 12 ), having a substantially rectangular plan, and a second body or rear body ( 14 ) designed to be connected to the first front body ( 12 ) and provided with opposed first and second substantially cylindrical appendages ( 16 ,  18 ) with a vertical passing-through hole ( 32 ) in which respective cylindrical bodies are inserted along which an offset and passing-through threaded hole ( 36 ) is bored, to form as many eccentrics ( 34 ), in each of said holes ( 36 ) being inserted a threaded stem or screw ( 38 ) that protrudes from the upper side of the front body ( 12 ) on which corresponding slots ( 32 ′) are made. 
     
     
       2. The sliding device according to  claim 1 , characterized in that each stem ( 38 ) comprises a lower threaded area ( 42 ), which is screwed into the hole ( 36 ) of the respective eccentric ( 34 ), and an upper threaded area ( 44 ), which protrudes from said slots ( 32 ′) made on the upper side of the front body ( 12 ), said lower ( 42 ) and upper ( 44 ) threaded areas being interspersed with a portion ( 40 ) without threading. 
     
     
       3. The sliding device according to  claim 2 , characterized in that on the lower side of the first body ( 12 ) there are slots ( 32 ″) aligned with the slots ( 32 ′) created on the upper side of the same body ( 12 ). 
     
     
       4. The sliding device according to  claim 2 , characterized in that on the upper threaded area ( 44 ) of the stem ( 38 ) projecting from said slots ( 32 ′) a nut ( 46 ) is screwed with interposition of a washer ( 48 ). 
     
     
       5. The sliding device according to  claim 2 , characterized in that from the lower side of each eccentric ( 34 ) a safety screw ( 50 ) is screwed into the respective hole ( 36 ) to prevent accidental transversal displacement of the eccentric itself. 
     
     
       6. The sliding device according to  claim 5 , characterized in that each safety screw ( 50 ) is screwed into the eccentric ( 34 ) starting from a slots ( 32 ″), formed on the lower side of the front body ( 12 ) and aligned with the slots ( 32 ′) created on the upper side of the same body ( 12 ). 
     
     
       7. The sliding device according to  claim 1 , characterized in that the first body ( 12 ), in correspondence of its rear side facing the second body ( 14 ), is provided with two recesses ( 16 ′,  18 ′) with semi-circular profile section complementary to that of the two substantially cylindrical appendages ( 16 ,  18 ) of said rear body ( 14 ). 
     
     
       8. The sliding device according to  claim 1 , characterized in that the rear body ( 14 ) comprises a third projecting substantially cylindrical appendage ( 58 ), centrally positioned with respect to the first and second cylindrical appendages ( 16 ,  18 ) and provided with a hole ( 60 ) at least partly threaded for a screw ( 62 ) on the head of which ( 64 ) a recess is formed shaped for an operating key and below said head ( 64 ) the same screw ( 62 ) carries an integral solid washer ( 66 ) designed to abut the upper side of the front body ( 12 ), on the rear side of the front body ( 12 ) being formed in parallel a recess with a substantially semicircular profile section ( 58 ′). 
     
     
       9. The sliding device according to  claim 8 , characterized in that the screw ( 62 ) cooperates with a threaded area ( 62 ′) created along the rear body ( 14 ). 
     
     
       10. The sliding device according to  claim 9 , characterized in that the head ( 64 ) of the screw ( 62 ) protrudes from a hole or slot ( 60 ′) formed on the upper side of the front body ( 12 ). 
     
     
       11. The sliding device according to  claim 10 , characterized in that at the opposite ends of said upper side of the front body ( 12 ) there is an adjustable stop ( 72 ), designed to avoid the door ( 24 ) from overriding the rollers ( 22 ) of the carriage or slider ( 10 ). 
     
     
       12. The sliding device according to  claim 1 , characterized in that a plurality of passing-through holes or slots ( 52 ) aligned with each other are provided on the front ( 12 ) and rear ( 14 ) bodies for the insertion of the same number of screws ( 54 ) designed to engage in the relevant expansion plugs ( 56 ) previously inserted into the wall ( 26 ) to secure to the wall itself the rear body ( 14 ), the holes or slots ( 52 ) created on the front body ( 12 ) and being sized so as to allow the passage of the head of said screws ( 54 ).
